Title: 修正錯誤的free_variable變數名稱

``` javascript
function outter(arg1) {
//arg1及free_variable1對inner函數來說，都是自由變數http://github.github.com/github-flavored-markdown/
var free_variable1 = 3;
return function inner(arg2) {
var local_variable1 =2;//arg2及local_variable1對inner函數來說，都是本地變數
return arg1 + arg2 + free_variable + local_variable1;
};
}
```

``` free_variable ``` changed as ``` free_variable1 ```
